Ferrites - any good use for them?
I've managed to accumulate about 25lbs of ferrite's that mainly came from old CRT's and a few other sources. I'm pretty sure they are mainly Fe3O4
and they are attracted to magnets which I believe is the normal property of Fe3O4 (FeO + Fe2O3 ??). The thing is I did a search of ferrites and on
the Google results page, it states it is Fe3O4 (per wiki) but the wiki page says it is Fe2O3, so IDK which it is or if the Fe2O3 is part of the
compound as stated above.
The ferrites are grey in color not rust color.
I was wondering if it is possible to make ferrate from this by using sodium hypochlorite and NaOH possibly?
Anyway, just wondering if there is anything interesting that could be done with these or if anyone has any experience with these.
There does seem to be the possibility of some Mn or Zn in the ferrites but it seems likely to be a low concentration.

Other than for r.f. circuits, almost all of the ferrites found in electronic components are Manganese-zinc ferrites http://www.fair-rite.com/about-us/company-history/history-of...
P.S. A digital multimeter on Ohms ranges will measure Mn-Zn ferrites as poor conductors, and Ni-Zn ferrites as poor insulators.

How can i make a shoe-rabbit out of potato skins and a bowl of pure CornFlakium and some ferroflufferite ?
Oh, wait a second.
Is this that Chemistry forum or is it RandomBollocks.com ?
(amazingly, NeverDoneShit.com is an available domain name right now)

Ferrites that are used on CRT tubes. There really isn't a wide variety of ferrites that are used for that purpose from what I read. Mainly composed
of Fe2O3 or Fe3O4 - wiki states both, so IDK which is the accurate compound. The fact that it is attracted to magnets makes me believe it is Fe3O4.

No, it's easier to make your Fe2O3 or Fe3O4
